Conformal Fe<sub>3</sub>O<sub>4</sub> Sheath on Aligned Carbon Nanotube Scaffolds as High-Performance Anodes for Lithium Ion Batteries
A uniform Fe<sub>3</sub>O<sub>4</sub> sheath is magnetron
sputtered
onto aligned carbon nanotube (CNT) scaffolds that are directly drawn
from CNT arrays. The Fe<sub>3</sub>O<sub>4</sub>–CNT composite
electrode, with the size of Fe<sub>3</sub>O<sub>4</sub> confined to
5–7 nm, exhibits a high reversible capacity over 800 mAh g<sup>–1</sup> based on the total electrode mass, remarkable capacity
retention, as well as high rate capability. The excellent performance
is attributable to the superior electrical conductivity of CNTs, the
uniform loading of Fe<sub>3</sub>O<sub>4</sub> sheath, and the structural
retention of the composite anode on cycling. As Fe<sub>3</sub>O<sub>4</sub> is inexpensive and environmentally friendly, and the synthesis
of Fe<sub>3</sub>O<sub>4</sub>–CNT is free of chemical wastes,
this composite anode material holds considerable promise for high-performance
lithium ion batteries
PDCD4 expression after IL-6 treatment.
<p>Levels of PDCD4 mRNA expression in LNCaP and PC-3 cells were downregulated after a 24-h treatment with IL-6 at 0, 5, or 10 ng/mL. The difference there was statistical significance (<b>a</b>) between each other. The same difference was also observed in the levels of PDCD4 protein expression (<b>b</b>). <b>(a)</b> PDCD4 mRNA expression of LNCaP and PC-3 cells was downregulated after a 24-h treatment with IL-6 at 10 ng/mL. <b>(b)</b> PDCD4 protein expression of LNCaP and PC-3 cells was downregulated after a 24-h treatment with IL-6 at 10 ng/mL,</p
PDCD4 protein expression in miR-21 inhibitor–transfected cells after IL-6 treatment.
<p>PDCD4 protein expression was significantly higher in prostate cancer cells transfected with the miR-21-inhibitor before Il-6 treatment than in cells not transfected with the inhibitor (one-way ANOVA test: <i>F</i> value = 241.781, <i>P</i> < 0.05). Levels of PDCD4 protein expression in transfected and nontransfected cells of both cell lines were significantly different (LSD test: <i>P</i> < 0.05).</p
